THE N80/2500 AND N90/2300: TWO WIND TURBINES FOR THE HIGHEST ENERGY YIELD.

With the N80/2500 and the N90/2300 you are enter-

ing new, hitherto unknown dimensions: a rotor

diameter of 80 metres or 90 metres and a rated

power of 2.5 MW and 2.3 MW respectively make the

N80/2500 and N90/2300 the first choice when it

comes to value for money. No matter whether they

are positioned inland, at the coast or in the offshore

area, these turbines produce optimal yields.

Our know-how in the megawatt class, acquired on

the basis of practical operation since 1995, made it

possible for us to develop the N80/2500 und

N90/2300 successfully.

The IEC-1a-certified N80/2500 suits perfectly for

high-wind regions. The N90/2300 is especially

suitable for lower wind locations. Thanks to

the pitch control, the machines are able to

optimise the energy yield at all wind speeds.

The N80/2500 and N90/2300 are supplied with

Nordex Control 2. Nordex Control 2 controls and

visualises all relevant data and, as a Web-based

system, it sets new standards in ease of use. All

our wind turbines are designed for a service life of

at least 20 years and are manufactured according

to ISO 9001.

THE N80/2500 AND N90/2300: THE FINER DETAILS AT A GLANCE.

Rotor

The rotor consists of three rotor blades made of

glass-fibre-reinforced polyester, the hub, the pitch

bearings, and drives to change the pitch angle of the

rotor blades.

Drive chain

The drive train consists of the rotor shaft, the gear-

box, an elastic cardanic coupling and the generator.

Gearbox

The gearbox is designed as a two-stage planetary

gearbox with a one-stage spur gear. The gearbox is

cooled by means of an oil-water-air cooling circuit

with stepped cooling capacity. The bearings and

tooth engagements are kept continuously lubricated

with cooled oil.

Generator

The generator is a double-fed asynchronous machine.

The generator is kept in its optimum temperature

range by means of a cooling circuit.

Cooling and filtration

The gearbox, generator and converter of the

N80/2500 and N90/2300 have cooling systems

which are independent from each other. The cooling

system for the generator and converter is based on

a water circuit. This ensures optimum operating

conditions in all types of weather.

Braking system

The three redundant and independently controlled

rotor blades can be set at full right angles to the

rotation direction for aerodynamic braking. In addi-

tion, the hydraulic disc brake provides support in

the event of an emergency stop.

Hydraulic system

The hydraulic system provides the oil pressure for

the operation of different components: the yaw

brakes, rotor brake and nacelle roof.

Nacelle

The nacelle consists of the cast machine frame and

the nacelle housing. The nacelle housing is made of

high-quality glass-fibre-reinforced polyester (GRP).

The roof of the nacelle is opened hydraulically.

Yaw system

The wind direction is continuously monitored by

two redundant wind direction sensors on the nacelle.

If the permissible deviation is exceeded, the yaw

angle of the nacelle is actively adjusted by means of

two geared motors.

Tower

The tubular steel tower is designed and certified as

a modular tower. The requirements of EN 50308 in

particular have been taken into account in the

design of the tower interiors (access ladder, plat-

forms, safety equipment). The transformer can be

installed either inside or outside the tower.

Control and grid connection

The wind turbine has two anemometers. One

anemometer is used for controlling the turbine, the

second for monitoring the first. All operational data

can be monitored and checked on a control screen

located in the switch cabinet. The data and signals

are transmitted via ISDN for remote monitoring. At

the click of the mouse, the operator can download

all key data for the turbine from the Internet. The

necessary communications software and hardware

is supplied by Nordex.

Lightning protection

Lightning and overvoltage protection of the entire

wind turbine is based on the lightning protection

concept and is in accordance with DIN EN 62305.
